Search for SUSY with missing ET and jets at CDF

Events with signatures involving large missing transverse energy (ET) are among the quintessential search modes for R-parity conserving supersymmetry. CDF has conducted two recent analyses for supersymmetry which use ET and jets. The ET and monojet signature is employed to determine process independent limits for the production of new physics beyond the Standard Model and then applied to models of spontaneous breaking of supersymmetry to determine limits on the supersymmetry breaking parameter and the gravitino mass. Direct searches for scalar top and scalar bottom quarks within the framework of supersymmetric models are performed using a signature of ET and two heavy flavor jets. Since the data is found to be consistent with Standard Model expectations, limits are determined in the mass planes m(tilde χ10)-m(tilde t1) and m(tilde χ1)0-m(tilde b1)
